LOUIS S. PARKE, OF BATAVIA, ASSIGNOR OF ONE-HALF HIS RIGHT TO ALVESHOFMANN, OF CHICAGO, ILLINOIS.

IMPROVEMENT IN MACHINES FOR FORGING HORSESHOE-NAILS.

Specification forming part of Letters Patent No. 215,768, dated May 27,1879; application filed October 16, 1877.

To all whom it may concern:

Be it known that I, LoUIsS. PARKE, of Batavia, Kane county, State ofIllinois, have invented new and useful Improvements in Machines forForging HorseshoeN ails, of which the following is a specification.

The nature of my invention consists in the construction and arrangementof a machine for forging horseshoe-nails, as will be hereinafter morefully set forth.

In the annexed drawings, to which reference is made and which fullyillustrate my invention, Figure 1 is a plan view of the machine. Fig. 2is a longitudinal vertical section of the same through the line 00 00,Fig. 1. Fig. 3 is a transverse vertical section through the line 3/Fig. 1. Fig. 4 is a plan view of the side hammers.

A represents the bed of the machine, formed or provided withsuitableguide-rails act, upon which the sliding frame or carriage B ismoved back and forth. In standards at or near the front end of thecarriage B is placed the driving-shaft O, to which the power is applied.This shaft carries in the center the ordinary rolling hammer b tooperate upon the top surface of the nail-rod, which is laid upon theanvil D, said anvil being attached to and forming part of the carriageB.

The driving-shaft O is further provided with eccentrics d d near theends, which, by means of pitmen E E, communicate the necessary motion tothe side hammers Gr. These hammers are adjustably attached to twolevers, G G, pivoted in the carriage, one on each side of the anvil, andtheir middle portions connected by links 6 c with a bail, f, whichlatter connects the lower ends of the pitmen E E together.

On one end of the shaft 0 is a pinion, h, which meshes with and drives alarge cogwheel, H, upon the end of a shaft, I, that has its bearings inand moves with the carriage B.

vUpon the shaft I is secured a cam, J, which works against a roller, i,mounted in the base or frame A for forcing the carriage forward. The camis held against the roller and the carriage mor'ed backward by means ofa lever, K, actuated by a spring, L, substantially as shown in Fig. 2.

On the side of thecam J is a projecting pin is supported in a hook, N,depending from a lug or pin, m, on the side of a rocking shaft, 0. Thisshaft is provided with an arm, 0, to which the cutter O is secured. Thecutter is raised again by means of a spring, P, bearing upon another lugor pin, a, projecting from the rock-shaft O.

On the shaft I is further secured a wheel or disk, K, having a cam orlug, p, on the periphery, and a similar one, 12, on the side near theperiphery. The cam 19 operates an L- shaped lever, B, which is pivotedin a slot at the forward end of the table S, over which the rod is fedto the machine, said table being firmly attached to the bed-frame A andpro jecting upward above the carriage B.

()n the side of the lever B, at the front end, above the table, ispivoted a block, 8, for holding down the rod on the table. A spring, T,bears on a lug projecting from the opposite side of the lever It at ornear the front end.

The cam or h1g1) operates an angular pivoted gage, V, to throw the sameinward a suitable distancein front of the cutter 0 W is a spring toreturn the gage to its position as soon as the cam 9 has passed. 0

Y is a stationary bent adjustable blade, against which the cutter 0works for cutting off the blank. Between this blade and the anvil is aspout, Z, through which the finished nails drop down under the machine.

that it does not move with the carriage and hammering devices, and,while the gage and the locking devices are operated by the movements ofthe machine, the nail-rod is fed up by hand.

The operation of the machine is as follows: The rod is placed on thetable S under the block 8, which holds the same firmly thereon. Thecarriage B being moved forward, and the cutter operated to cut off onenail, the lug p at this moment strikes the lever B, raising the block 8,and almost at the same instant the gage V is thrown inward by the lug p.The

The ta ble S is attached to the bed or main frame, so

operator then pushes the rod inward against said gage, when the gagemoves outwardagain, and the block 8 is pressed down upon the blank bythe action of the spring T. The carriage now moves backward, whichbrings a portion of the rod suflicient to form a nail on top of theanvil D, where the same is hammered by the rolling hammer b and sidehammers Gr G. The carriage then moves forward again,which withdraws theanvil from under the nail and brings the cutter up to the hammeredportion of the rod. The cutter 0 then descends and cuts off thecompleted nail, which falls down through the spout Z under the machine.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination of the shaft 0, provided with the eccentrics d d, thepitmen E E, bail f, links 0 e, and pivoted levers G G with theadjustable side hammers G G and the anvil D, all constructed andarranged upon a movable carriage, B, substantiallyas and for thepurposes herein set forth.

2. The rock-shaft O, with arm 0, carrying the cutter O in combinationwith the shaft I, cam J, with pin 70, lever M, hook N, spring 1?, andpin a, all constructed and arranged substantially as and for thepurposes herein set forth.

3. The combination of the shaft 1, disk K, With cams p p, lever B, withpivoted block 8, the gage V, and spring W, all constructed and arrangedto operate substantially as and for the purposes herein set forth.
